Twelfe Progessive Duets for Two Es-Tubas (Treble clef) This collection of Twelve Progressive Duets for Two Eb Basses (or Two Bb Basses) is designed to introduce new Eb or Bb Bass players to duet playing starting from the most basic type of duet, simple imitation, through to more complicated musical ideas involving independent two-part writing. Duets are a very useful teaching tool as they introduce many musical skills such as playing with varied dynamics, playing with varied articulations and playing in a musically cooperative and balanced way with others. This requires good listening skills as well as good playing skills, both of which are required to become an effective and reliable member of a larger ensemble such as a band or an orchestra. The book contains a collection of 12 original duets written in variety of popular styles and are suitable for two Eb (or two Bb) Bass players players from Grade 3 upwards.
